Thanks for any response jim. For example if a 3v and a 9v battery were wired in parallel the output voltage would be 6v 93 divided by 2 however the current will be total amperage of all.
How To Install A 9v Battery
2 9v batteries connected. If you were to connect a device to the battery bank it is capable of powering say a 05 amp. The first practical outcome is that the amp hour capacity will be the lowest of the batteries connected together. Jim k good morning i have 2 batteries connected together to make 24 volts for my trolling motormy question is can i use 1 battery for my outboard for a 12 volt starting and charging system without disconnecting the 2 batteries. In the example above this would be the 52 ah battery. At my house i took two 9v batteries and connected them in line with each other to the switch. I bought a 12v light and a pushbutton switch at the store.
I then connected the light to the switch and soldered both the wires from the batteries and the light to the switch. Unlike wiring batteries in series when batteries are wired in parallel the voltage does not increase the output voltage is the average voltage of all batteries in the circuit. Not a disaster if you were only expecting 5 ah at least not a problem right away. For a school physics project not much electrical experience i have decided to create a light saber. If you connect them as series connection scheme then you will have a 18 volts battery or 0 volt battery depending on electrodes connected together if you connect them parallel positive to positive and negative to negative then you have a 8 volts battery that lasts twice but if they are connected parallel but positive to negative then they start discharging and heat will be generated.
